A device that relieves lubricant pressure in a divider block lubrication system into a fluid reservoir, a container, or directly back into the compressor frame to which the tubing is connected. The unused portions of the polychromatic light are re-reflected for transmission through a different spatial region of the light filter, resulting in an approximately 30% increase in probability of transmission. During operation, the first coherency domain receives a flush operation broadcast to the first and second coherency domains, where the flush operation specifies the target address of the target memory block. Upon detection of a fault, the hardware automatically reissues the read access to a separate memory bank that is logically identical to the faulty bank.
